Thanks very much for your suggestions and hints.

About the second part of the problems I have changed in this way (I realized that it should be broken because sometime the buttons fonts were mangled).

I used a mix of your tips using event "PLAYER_LOGIN" and then unregister once fired.

local frame = CreateFrame("Frame")
frame:RegisterEvent('ACTIVE_TALENT_GROUP_CHANGED')
frame:RegisterEvent('PLAYER_SPECIALIZATION_CHANGED')
frame:RegisterEvent("PLAYER_ENTERING_WORLD")
frame:RegisterEvent("PLAYER_LOGIN")
frame:SetScript("OnEvent", function(self, event, ...)
    BuildActiveSpec()
    UpdateLDB()
        
    if event == "PLAYER_LOGIN" then 
        BuildMenu()
        frame:UnregisterEvent("PLAYER_LOGIN")
    end
end
)

Uhm ...

This works but is so ugly ?

Menu:SetScript('OnLeave', function()
    local name = GetMouseFocus():GetName() or tostring(GetMouseFocus())
    if string.sub(name,1,6) ~= "table:" then Menu:Hide() end
end)

The problem is when I hovering the buttons the "name" var is something like:
table:00000149a7cf46e0

or if I exit from the frame values I get are:
WorldFrame
ChocolateBar1
etc etc ...

Thanks anyway for your suggestions.
